Liquid nitrogen quick freezing and emergency treatment

Emergency treatment

　　Emergency treatment: Quickly evacuate the upper wind of the leakage contaminated area, isolate it, and strictly restrict access. It is recommended that emergency personnel wear self-contained positive pressure breathing apparatus and wear cold-proof clothing. Do not directly touch the leakage. Cut off the source of leakage as much as possible. Use an exhaust fan to send the leaked air to an open place (liquid nitrogen quick freezing). Leaking containers should be properly handled and used after repair and inspection.

　　 Liquid nitrogen leakage treatment method

Inhalation (liquid nitrogen quick-freezing) when the nitrogen concentration is not too high, the patient* initially feels chest tightness, shortness of breath, weakness, and then irritability, extreme excitement, running around, yelling, trance, and unsteady gait, which is called "nitrogen "酩酊", can enter a state of lethargy or coma. Inhalation of high concentrations, patients can quickly become unconscious and die due to the arrest of breathing and heartbeat.

  1. Quickly evacuate personnel in the leaked contaminated area * upwind, and set up isolation areas to strictly restrict access.

  2. Notify the fire and related units.

　　3. Emergency response personnel should wear self-contained positive pressure breathing apparatus, winter clothes, and winter gloves.

　　4. Avoid leakage of liquid into the basement or other confined work spaces. If it is unavoidable, notify the relevant department immediately.

　　 5. Do not directly touch the leakage.

　　 6. Cut off the source of leakage as much as possible.

　　7. Water spray can be used to accelerate the evaporation of the liquid, but the water gun can not be used to shoot the liquid.

  8. To prevent gas from accumulating in low recesses, use an exhaust fan to send the leaked gas to the open space.

  9. People are prohibited from staying in low-lying or downwind areas.
